Hi,

copyEndy

We'll say that a positive int n is "endy" if it is in the range 0..10 or 90..100 (inclusive). Given an array of positive ints, return a new array of length "count" containing the first endy numbers from the original array. Decompose out a separate isEndy(int n) method to test if a number is endy. The original array will contain at least "count" endy numbers.

We'll say that a positive int n is "endy" if it is in the range 0..10 or 90..100 (inclusive). //so output array elements should always be between 0 till 10 or 90 till 100?but what is length of output array?how we know(looks like it is count)?
Given an array of positive ints, return a new array of length "count" containing the first endy count numbers from the original array.//first endy count numbers means what??
